When people hear about elder abuse in nursing homes, they usually think of staff members victimizing residents. However, research by Cornell University faculty members suggests that a more prevalent and serious problem may be aggression and violence that occurs between residents themselves.

Although such aggression can have serious consequences for both aggressors and victims, the issue has received little attention from researchers, and few proven solutions exist to prevent resident altercations, says Karl Pillemer, director of the Cornell Institute for Translational Research on Aging at the College of Human Ecology. He has co-authored two articles -- in Aggression and Violent Behavior and in the Journal of the American Geriatrics Society -- on "resident-to-resident mistreatment" this spring with Weill Cornell Medical College professor of medicine Mark S. Lachs, M.D., and medical student Tony Rosen. Both studies report that verbal and physical aggression between residents is common and problematic, and that more research is necessary to identify risk factors and preventative measures.

"Anyone who spends much time in a nursing home will observe arguments, threats and shouting matches among residents, as well as behaviors like pushing, shoving and hitting," Pillemer said.

Researchers have demonstrated the possibility of preventing the human malaria parasite, Plasmodium falciparum, which is responsible for more than a million malaria deaths a year, from becoming sexually mature.

The discovery could have implications for controlling the spread of drug resistance, which is a major public health problem and which hinders the control of malaria.

The life cycle of Plasmodium falciparum is complex, and it is not yet known what triggers the production of parasite gametes or sex cells. These sexual forms of the parasite do not contribute to malaria symptoms, but are essential for transmission of malaria between humans via the bite of a mosquito.

In 1928 Alexander Fleming discovered penicillin, which was subsequently developed into a medicine by Florey and Chain in the 1940s. The antibiotic was hailed as a 'miracle cure' and a golden age of drug discovery followed. However, frequent rediscovery of known natural products and technical challenges forced pharmaceutical companies to retreat and stop looking for new molecules.

Big pharmacy companies gave up on soil bacteria as a source of antibiotics too soon, according to research published in the June issue of Microbiology. Scientists have been mining microbial genomes for new natural products that may have applications in the treatment of MRSA and cancer and have made some exciting discoveries.

"Over the last eight years we have been looking for new natural products in the DNA sequence of the antibiotic-producing bacterium Streptomyces coelicolor," said Professor Gregory Challis from the University of Warwick. "In the last 15 years it became accepted that no new natural products remained to be discovered from these bacteria. Our work shows this widely-held view to be incorrect."

A new survey reveals more than three quarters - 84% - of the country's mums are unknowingly teaching their kids the incorrect routine when it comes to handling coughs and sneezes.

However, we all know mums want the best for their family so help is now at hand in the form of a new children's booklet featuring popular character Dirty Bertie and a new nursery rhyme teaching children how to avoid spreading germs.

The UK will need to attract more highly skilled workers from abroad - both from the European Union and outside it - in order to secure the future of high technology, 'knowledge intensive' industries in an increasingly global world, a new report finds today.

The UK has to date been successful as a location for foreign investment, but a combination of increasing demand for 'knowledge workers', especially in IT, science, healthcare and technology fields, skill shortages among employers, and an ageing population, means policymakers must do more to ensure the UK remains an attractive place for highly skilled migrants to want to come.

Unite, Britain's biggest union is urging the government to act to make pension schemes compulsory, as a survey of voters in key marginal seats reveals that action on pensions will influence their voting preferences in the next general election.

In a survey of constituents in the twenty most marginal Labour seats in the UK, conducted on behalf of Unite, half of those surveyed stated that action by a political party to protect occupational pension schemes would influence their voting intentions. 34% of voters in these critical constituencies have yet to decide which party best represents their interests.

A major contribution to the long-term storage and access of data on mutation for genes and disease has been established with the launch of Human Genomics and Proteomics, the first database journal affiliated with a database, FINDbase: the National/Ethnic Mutation Database documenting frequencies of causative mutations leading to inherited disorders in various populations worldwide.

The first title to be launched through SAGE-Hindawi – the joint collaboration between SAGE and Hindawi Publishing Corporation, Human Genomics and Proteomics (HGP) is a peer-reviewed international open access journal that will provide a unique forum for the discussion of research on human genomics and proteomics, systems biology and various aspects of personalized medicine.

One copy of the human genome is more than 3 billion nucleotides in length, and weighs in at about 3.5 picograms (pg, or trillionths of a gram). Only about 1.5% of this is composed of our 20,000 or so protein-coding genes, though other data suggest that at least 5% has been conserved by natural selection, suggesting that a notable portion of the non-coding majority is also functional. On the other hand, it is now apparent that much of the genome residing in our cells is made up of sequences like transposable elements -- "parasites" of the genome that can move about wwithin and be copied independently of the "host" genome -- and especially their extinct remnants. One such element, Alu, is present in more than one million copies.

The discovery of four families in which some members only walk on all fours (quadrupedality) may help us understand how humans, unlike other primates, are able to walk for long periods on only two legs, according to professor Tayfun Ozcelik, of Bilkent University, Ankara, Turkey, who presented his study at the annual conference of the European Society of Human Genetics tomorrow.

The quadrupedal families in Turkey previously attracted attention in 2005, when they were discovered. Now the Turkish team reports that they have found the first gene implicated in quadrupedal locomotion in these families.

Ozcelik and colleagues, studied four unrelated families where some members were affected by the rare quadrupedic condition, Unertan syndrome, which is also associated with imperfect articulation of speech, mental retardation, and defects in the cerebellum, a part of the brain involved in motor control. They found that the affected individuals in two families had mutations in the gene responsible for the expression of very low density lipoprotein receptor (VLDLR), a protein which is known to be critical to the proper functioning of the cerebellum during development.
